i want write vnc client , server think learn lot. want in java saw somewhere isn't possible. i'd want use c++ parts aren't possible in java. i'm little confused begin. saw tightvnc,realvnc etc code base large me make sense. see rfb specifies packet types me started? how go writing code make packet formats of use? explain if this vnc server?

i have question: if ditch rfb can write

1. a server application: captures on screen , sends client every few milliseconds. (robot screencapture slow) , waits mouse movements , keystrokes.
2. a client application sends mouse movements , keystokes server , displays screen of server. i'm worried synchornization.
